Math::Symbolic::Custom::Transformation is an extension to the
Math::Symbolic module. You're assumed to be remotely familiar with that
module throughout the documentation.
This package implements transformations of Math::Symbolic trees using
Math::Symbolic trees. I'll try to explain what this means in the following
paragraphs.
Until now, in order to be able to inspect a Math::Symbolic tree, one had
to use the low-level Math::Symbolic interface like comparing the top
node's term type with a constant (such as T_OPERATOR) and then its
operator type with more constants. This has changed with the release of
Math::Symbolic::Custom::Pattern.
To modify the tree, you had to use equally low-level or even
encapsulation-breaking methods. This is meant to be changed by this
distribution.
